On my system (Linux) this works unpredictably,sometimes the desktop shortcut is created successfully,some other times instead it creates a weird text file on the desktop,as it happens with this very same site:if I drag the favicon on the desktop,it triggers a process similar to a file copy operation and the final result is this weird text file that looks like a summary of the page source.

Is this a known bug,and are there any possible workarounds,even using an extension?
